I have a Pentair Whisperflo setup on my pool. This past summer the motor has been sounding loud, took propeller apart thinking maybe there was stuff in there but it was clean. Yesterday it wasn't on and noticed it had tripped the breaker so i reset the breaker and when I turned on the pump it just made this loud noise, the shaft spins freely so I decided to replace the capacitor, well still making that loud noise when power turned but got the motor to run but it sounds bad. The motor is 2 years old and should not of gone bad this quick. Do I need a new motor? Thanks in advance!!!!
